IMPROVEMENT IN INKSTANDS.

Specification forming part of LettersPateut No. 51,931, dated January 9, 1866 reissue No. 4,197, dated December 13, 1870 reissue No. 7,127, dated May 23, 1876; application filed August 24, 1874.

To all whom it may concern:

Be it known that I, SAMUEL DARLING, formerly of Bangor, Maine, but now of the city of Providence, in the State of Rhode Island, have made certain new and useful Improvements in Inkstands; and I do hereby declare the same to be fully described in the following specification and illustrated in the accompanying drawing, in which Figure 1 is a topyview; Fig. 2, a side elevation, showing the cover as raised; and Fig. 3, a longitudinal section of an inkstand constructed in accordance with my invention, this latter section being taken through the dipping-cup and its vent-hole.

der-side view of the fountain or upper portion Fig. 4 is an unof the inkstand- Fig. 5 is a top view of the lower portion of said stand; and Fig. 6 is a longitudinal section taken when the ink is low, and the ink-fountain has been turned around about one hundred and eighty degrees from the position shown in Fig. 3.

The, nature of my improvement consists, first, in an inkstand having a reservoir arranged so as -to be capable of being rotated upon its bed or stand, and having a pen-dipping cup on one side of its center of rotation, when the ink is caused to beat the proper height in the dippingcup by revolving the reservoir; and, second, in an inkstand having a' dipping-cup the lower part of which is smaller than the breadth of .a pen, and having, also, an ink-containing cavity or recess in the bottom of the reservoir, located under the dipping-cup, all as hereinafter more fully, set

forth; third, in an inkstand having a dippingcup the lower part of which extends down.

into the ink, and is smaller than the breadth of a pen, and having, also, an opening for the passage of air to or from the reservoir.

In carrying out my invention, I construct the body portion of my inkstand in two parts, I as follows:

In the drawing, A denotes the upper, and B the lower, portion of the inkstand, each portion being of a frusto-oonical or other proper shape, the plane of the bottom of part A and the plane of the top of part B being, when the parts are in place for use, equally inclined to the horizon. For the purpose of hiding the joint between the said parts, a rim or head, 8,

. "may be formed around either of the said upper or lower portions. The part A is made hollow, or is chambered, so as to constitute a fountain or reservoir, 0, for the ink, such fountain increasing in depth from its front to its' rear part. as seen iii'Fig. 3, and being provided with a bottomless pen-passage or dipping-cup, a, leading upward from the same; This (lipping-eup tapers downward, and is immersed in the ink, as shown; and the opening at its lower part is made less in diameter than a pen, so that while the tip or nib of the pen may project below it, yet the thicker part of the pen will'positively arrest or limit its downward movement.

It is obvious that this opening may be made in various shapes without affecting the invention. A cavity or'recess, c, is made in a nippleor projection, 12, which extends downward from the lower face of the part A, as shown in Figs. 3 and 4. This cavity or chamber is located directly underneath the dipping-cup, which is of a hollow frusto-conical shape, and projects downward from the top of the reservoir, into which it opens, as seen.

The object of making this chamber -0 directly below the pen or dipping cup a, in connection with the small diameter given to the opening at the bottom of such cup, is that the pen may descend to the lowest ink in the reservoir without injury to its point, or coming in contact with'the sediment that may be deposited or thrown down from the ink. D is another cylindrical projection or pin, projecting axially downward from the lower face of the fountain or upper portion A, and entering a hole or socket, 0, formed through the part B, as seen in Fig.5. The said pin serves to connect the two portions A and B,.and at the same time to allow either of the said parts to be freely rotated. In the upper surface of the said part B an annular groove or channel is formed, such being for the reception of the projection 12', containing the sediment-chamber c, hereinhefore mentioned, and for allowing such projection to be moved throughout such groove during 'an entire revolution of the part A on the part B. e is a vent-hole, which opens out of the upper part of the dippingcup, and communicates with the interior of the ink-fountain.

- ping or pen cup, I provide such cup with a self-adjusting and self-closing valve or cover, G, which I suspend from the central part'of a curved wire or bail, H, the two extremities of such bail being jointed or pivoted to opposite sides of the part A, as shown in Fig. 1.

This valve or cover should be so hinged or jointed to the bail that whenever the hand .of a person, after having efi'ected the elevation of the bail, so as to raise the cover off the mouth of the inkstand, may have been withdrawn from the arm I of the bail, the gravitating power of the bail and its arm and the'cover shall cause them to'descend, and the cover to close thesaid mouth. The lever" or arm I is slotted or'fastened to the bail H near'its central part, and extends'up.

ward therefrom, as seen in Fig. 1. This'arm or lever should be of such form" and soarranged that it may be conveniently and readily metby the hand of aiperson while in the act of being moved toward the inkstand for the purpose of inserting a pen therein, the

pressure of the hand against the-arm serving, under such circumstances, to raise thebail and its cover, so as to open the mouth of the inkstand" for the introduction of the pen there in. During the act of withdrawing'thepen and hand from the inkstand the bail and,

cover will descend, so as to-carry the cover on and cause it to close the mouth. v

When the inkstand is tobe charged "with ink, the fountain or part A is to be turned until the top surface thereof shall stand in a horizontal plane. The ink'is next to be poured into the fountain until it shall become full enough, which will be indicatedby'its standing atthe desired height-infthedippingcup. This having been done, all thatis requisite to maintain the ink at the requiredlevel in the dipping-cup, as its quantity diminishes, is to simply turn the .part A from time "to timeuponitsfellow, B, as circumstances may require.

From the above itwillbe seen that-my iln= provedinkstand isnot "only simple in construction and capable'of beingreadily charged with ink, but such ink can easily be main tainedat the desired heightinthedippin gcu-p,

notwithstanding the-quantity in the reservoir may be steadily diminishing, thus insuring that the pen shall always takehp a proper supply, but never an oversupply, while'atthe same time the ink in the reservoir is-most efl'ectually protected from dust-or other for-' eign matters.

I do not claim an inkstand made with its ink-holder and its base applied together with inclined surfaces and a pivot at the junction; nor do I claim the arrangement and combination ofa how-"lever with a cover hinged directly to the pen part, ring, or cap of an inkstand, thesame being as represented in the United States Patent No. 13,515.

I do not claim an inkstand or ink-well havinga dipping-cup the lower part of which extendsdown into the ink when in use,a small openingabove the ink for the circulation of air, and an ink-cavitybelowthe bottom of the reservoir, when such an inkstand or several of such are inclosed in'a shell or case, and the main part of such well is open and exposed to the air within the case or shell, as my invention does not relate to such an arrangement. What I claim as my improvement or invention'is as follows:

1.. An inkstand, having an ink-reservoir arranged to be rotatedhorizontally upon its .bed 'or stand, and having a dipping-cup on one side of its center of rotatiomso that the ink may be caused to stand at the proper height inthe dipping-cup by revolving'the reservoir, substantially as described.

2.The combination, in an inkstand, ofan ink-reservoir, a' di ppin g cup or -tube, the lower diameter or opening of which is less than the width-of an ordinary writing pen, and. an inkwell or recess in the bottom of the reservoir under the dipping-cup, substantially as described, and for the purpose herein set forth. 3. The combination, in an inkstand, of an ink-reservoir, a dipping cup,the lower diameter or opening 'ofwhich is less than the width of an ordinary writing-pen, through which there is an open communication with the interior of the reservoir, and also an opening for the freeTpas'sage-of air to and ,from"theink-reservoir, substantially as and for the. purpose herein described.

: 4.'The combination, in an inkstand, of an ink reservoir, a dipping-cup, the lower part i of which extends'down'ward into the ink when inuse,-and through the lower part of which there 'is'an open communication with the ink in thereservoir, an ink cavity or well "in and below the bottom of the main-reservoir under the dipping-cup, and an opening" above the ink for' the free passage of air to orfrom the SAMUEL DARLING.
